It's hard to imagine getting a virus from anywhere else, Android is isnt popular enough, ie most virus/malware you will find online are targeted towards windows
And that's hitting the mail on the head.
Android may not be as popular as Windows, but loot at how popular it is on the cell phone market. Then, remember how much more people are using their cell phones to do things they use to only do on a pc. There's a reason cell phones have cut into the computer market. Tablets and smartphones have started the home computer down a spiral staircase, so you can rest assured that malware & viruses will start their major ascent pretty soon.
